• Pressure and compacting turn the peat into limestone with fossils.

• Compacting and cementation turn the peat into shale.

• Melting and cooling turn the peat into granite.

• Pressure and heating turn the peat into coal.

 Why a builder would use a synthetic material like concrete, instead of quarried stone while constructing a building.

• Concrete is more expensive than stone, so it is more desirable.

• Concrete weighs more than the same amount of stone, so it is stronger.

• Concrete is a synthetic material, so its use does not deplete natural resources.

• Concrete can be readily poured into a desired shape, so it is easier to work with.

 How did the Haber process lead to increased farm yields?   

• Synthetic ammonia compounds are better for plants than naturally occurring compounds.

• The use of the Haber process allows animals to be used as food instead of using them to produce fertilizer.

• The Haber process uses nitrogen from the air so plants can use its products faster than ammonia from other sources.

• Synthetic ammonia compounds are available in greater quantities than naturally occurring compounds.
